Gosh, it sounds like to solve this horrible problem you would institute
the eugenics of extreme century social darwinism.

In the long run intelligence is randomly distributed. I don't believe
that the normal distribution for IQ has shifted to the left over time.

We are probably better prepared to solve crop failures due to disease,
mainly through genetic technology, than ever before in history

Problems, problems, problems...Human history has your answers.

It's refreshing to see a budding neo-malthusian blathering their way
toward the formation of a philosophy of doom.
World, behold, the next Malthus; stand aside Ehrlich, back away Meadows,
our next author of millennialist nonsense has arrived, I present Tracy
